Embodiment 2

[0058] The proportion of oil-coal slurry is 4.0g of coal powder, 6.0g of solvent, and 0.15g of catalyst. The target setting temperature is 450°C, and the reaction residence time is 40min. The rest of the steps are the same as in Example 1.

Embodiment 3

[0060] The proportion of oil-coal slurry is 5.0g of coal powder, 6.0g of solvent, and 0.15g of catalyst. The target setting temperature is 455°C, and the reaction residence time is 60min. The rest of the steps are the same as in Example 1.

[0061] In the specific implementation, open the miniature high-pressure reactor, according to the technical requirements of direct coal liquefaction, fill an appropriate amount of raw materials, tighten the high-pressure flange, and seal the high-pressure reactor to ensure that there is no gas leakage under the reaction pressure; use low-pressure nitrogen, hydrogen Purge the reaction system, then fill the reactor with gas at normal temperature to a certain pressure; open the high-pressure reactor to stir; raise the salt bath furnace to the set temperature in advance, quickly raise the elevator, and raise the salt bath furnace so that the salt The bath submerges the entire autoclave, so that the autoclave rises to a certain temperature, and ...

Abstract

The invention relates to a miniature high-pressure reactor experiment device for coal hydro-liquefaction and an experiment method thereof. The device comprises a miniature high-pressure reactor, a support and a salt bath furnace, wherein the miniature high-pressure reactor comprises a miniature high-pressure reactor body, a high-pressure reactor cover and an agitating system, and the volume of the miniature high-pressure reactor is from 100ml to 200ml; the miniature high-pressure reactor is fixedly suspended on the support through the high-pressure reactor cover; the salt bath furnace is located below the miniature high-pressure reactor and is used for indirectly heating the miniature high-pressure reactor body by heating fused salt through an electric heating furnace tube, and the salt bath furnace is arranged on an elevating platform. The invention comprehensively considers the accuracy parameters of a coal hydro-liquefaction intermittent high-pressure reactor experiment in a laboratory capable of rapidly heating, such as volume of the high-pressure reactor, reaction heating rate, temperature control and the like. Compared with the prior art, the invention associates the accuracy of experiment data to the heating rate together for the first time and has high accuracy and simple operation.

Description

technical field [0001] The invention relates to the technical field of direct coal liquefaction, in particular to a miniature high-pressure reactor experimental device and an experimental method for direct coal liquefaction, so as to realize rapid temperature rise. Background technique [0002] The sharp rise in world oil prices, oil consumption, and depletion of oil resources has forced the energy industry to consider alternatives that can replace petroleum fuels. Coal is one of the most abundant hydrocarbon resources on earth, and coal can be converted into liquid fuels through hydrogenation reactions. Coal direct liquefaction is a process in which coal, catalysts, and solvents are hydrogenated into liquid fuels and other chemicals in the reaction under high temperature and high pressure conditions. With the development of direct coal liquefaction technology, a new generation of direct coal liquefaction technology is characterized by milder reaction conditions and higher ...
